Title: Pole top cover expandable bracket assembly
Inventor: THORNTON GERRY F
IPC: E04H12/22
Filed: 1993-02-16
Abstract: POLE TOP COVER EXPANDABLE BRACKET ASSEMBLY               ABSTRACT OF THE DISCLOSURE   A pole top cover assembly includes a generally flat cover plate adapted to overlie an open top end of a tubular  hollow  pole,  an  elongated  arcuate-shaped bracket  formed  of  yieldably  resilient,  semi-rigid, semi-flexible deformable material and being disposable along one side of the cover plate,  and an elongated fastener rotatably mounted through both an aperture in the cover plate and a hole in the bracket and having external threads threadably engaged with portions of the  plate  and  bracket  which  form  the  respective aperture and hole thereof.  Rotation of the fastener in one direction relative to the cover plate and bracket causes the arcuate-shaped bracket to engage the plate and to deform and draw toward the one side of the cover plate and thereby expand in length and forcibly engage at opposite ends with portions of an interior surface of the hollow tubular pole so as to retain the cover plate on the pole top end.  Rotation of the fastener in an opposite direction relative to the cover plate and bracket permits the arcuate-shaped bracket to engage the plate and to reform and retract away from the one side of the cover plate and thereby contract in length and disengage at the opposite ends from the portions of the interior surface of the hollow tubular pole so as to release the cover plate from the pole top end.

Title: Ultrasonic Transducer Assembly
Inventor: OKUNUKI KAZUMICHI
IPC: G01N29/26
Filed: 1993-05-26
Abstract: An ultrasonic transducer assembly comprises a transducer unit having an array transducer composed of a plurality of transducer elements for transmitting and receiving ultrasonic waves to effect electronic scanning. and a casing for housing the transducer unit therein.  The casing has a contact surface to be brought into contact with an object to be examined, and in the casing there is disposed a swing mechanism for swinging or pivoting the transducer unit with respect to a virtual rotative axis which is determined on an electronic scanning plane produced by the array transducer and in the vicinity of the contact portion of the casing.  The swing mechanism includes a pair of guide members formed with arc-shaped guide routes concentrically arranged with the virtual rotative axis as its center, a linking mechanism for linking the transducer unit with the guide members in such a way that the transducer unit can be pivoted or swung along the arc-shaped guide routes of the guide members with respect to the virtual rotative axis; and a driving mechanism for reciprocatingly moving the transducer unit along the arc-shaped guide routes of the guide members.  In this  ultrasonic transducer assembly, a three-dimensional echo data acquiring region can be produced based on the shift of the electronic scanning plane with the virtual rotative axis as its center by the swinging mechanism.  The virtual rotative axis is located in the vicinity of the contact surface of the casing.  Therefore, when the contact surface of the transducer assembly is brought into contact with the body surface between the ribs of a patient to be examined, it is possible to acquire three-dimensional echo data through the space between the ribs, without being subject to the influence of the presence of the ribs.
